在iOS上用户的Facebook个人资料上分享照片

Question

我正在尝试将我的应用程序中的照片分享到Facebook，就像Instagram一样，通过切换“在Facebook上分享”，用户可以在墙上拍摄漂亮的大照片。

我在Facebook上完全遵循了“开放图形的自定义故事”教程： https://developers.facebook.com/docs/ios/open-graph

我甚至在iOS上按照教程代码下载了Facebook的示例项目。我复制了这段代码并用我的命名空间替换了命名空间，动作和对象。这是代码：

// stage an image
  [FBRequestConnection startForUploadStagingResourceWithImage:image completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    if(!error) {
      NSLog(@"Successfuly staged image with staged URI: %@", [result objectForKey:@"uri"]);

      // instantiate a Facebook Open Graph object
      NSMutableDictionary<FBOpenGraphObject> *object = [FBGraphObject openGraphObjectForPost];

      // specify that this Open Graph object will be posted to Facebook
      object.provisionedForPost = YES;

      // for og:title
      object[@"title"] = @"Roasted pumpkin seeds";

      // for og:type, this corresponds to the Namespace you've set for your app and the object type name
      object[@"type"] = @"fbogsample:dish";

      // for og:description
      object[@"description"] = @"Crunchy pumpkin seeds roasted in butter and lightly salted.";

      // for og:url, we cover how this is used in the "Deep Linking" section below
      object[@"url"] = @"http://example.com/roasted_pumpkin_seeds";

      // for og:image we assign the uri of the image that we just staged
      object[@"image"] = @[@{@"url": [result objectForKey:@"uri"], @"user_generated" : @"false" }];

      // Post custom object
      [FBRequestConnection startForPostOpenGraphObject:object completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
        if(!error) {
          // get the object ID for the Open Graph object that is now stored in the Object API
          NSString *objectId = [result objectForKey:@"id"];
          NSLog(@"object id: %@", objectId);

          // create an Open Graph action
          id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
          [action setObject:objectId forKey:@"dish"];

          // create action referencing user owned object
          [FBRequestConnection startForPostWithGraphPath:@"/me/fbogsample:eat" graphObject:action completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
            if(!error) {
              NSLog(@"OG story posted, story id: %@", [result objectForKey:@"id"]);
              [[[UIAlertView alloc] initWithTitle:@"OG story posted"
                                          message:@"Check your Facebook profile or activity log to see the story."
                                         delegate:self
                                cancelButtonTitle:@"OK!"
                                otherButtonTitles:nil] show];
            } else {
              // An error occurred, we need to handle the error
              // See: https://developers.facebook.com/docs/ios/errors
              NSLog(@"Encountered an error posting to Open Graph: %@", error.description);
            }
          }];

        } else {
          // An error occurred, we need to handle the error
          // See: https://developers.facebook.com/docs/ios/errors
          NSLog(@"Encountered an error posting to Open Graph: %@", error.description);
        }
      }];

    } else {
      // An error occurred, we need to handle the error
      // See: https://developers.facebook.com/docs/ios/errors
      NSLog(@"Error staging an image: %@", error.description);
    }
  }];

这是日志：

问题是，即使对象显示在对象浏览器中，帖子永远不会进入我的墙，。转到developers.facebook.com上的应用仪表板并打开图表，我看到故事存在，但即使应用程序这样说，也没有共享故事。

怎么了？求救！
